LAND CL 3 AND OULTIVATOR a.

CHINE Application filed November 4%, 1822. Serial m. 599,026.

To all whom it may concern:

Be it known that I, DUNCAN JOHN CAMP- BELL, a subject of the King of Great Britain, and a resident of Glasgow Station, in the Province of Ontario and .Dominion of Canada, have invented certain new and useful Improvements in Land Cleaning and Cultivator Machines, of which the following is a specification.

lhis invention relates to improvement in land cleaning and cultivator machines, and the objects of the invention are to provide a machine for removing scutch or quack grass, weeds and the like from farm land.

Further objects are to provide a machine of this kind for tillage farm which will, while effectively removing all dirt in the form of weeds, scutch grass and the like, at the same time perform the functions of e cultivator.

A still further object is the provision of an economically constructed cleaning and cultivating machine in which the several parts are so arranged as to perform the functions required of them in a thoroughly satisfactory and permanent manner.

With the foregoing and other objects in view, the invention consists essentially in the novel construction and arrangement of parts as described in the present specification and illustrated by the accompanying drawings that form part of the same.

Referring to the drawings, in which like characters of reference indicate corresponding parts in each figure, and in which:

Figure 1 is a side elvation.

Figure 2 is a plan View. 7

F i re 3 is a cross-section on the line 3-3 of Figure 1.

Figure 4 is a longitudinal section of the roots and weed box.

Figure 5 is a cross-section of same, showing a portion of the screens.

Figure 6 is an enlarged plan of the upper end of the conveyers and shaker screens.

Figure 7 is a longitudinal section of same.

Figure 8 is an enlarged plan of the forward frame, partly sectional.

Figure 9 is a longitudinal section of same.

In the drawings:

The machine as a whole is designated by the letter A and comprises (as shown in Figures 1 and 2) a frame 10 mounted on wheels 11 on an axle l1 and provided with a caster wheel 12 whereby the front of the machine can be raised or lowered. Mounted on the body or frame 10 is a skeleton frame 13 combinin the side pieces 14, top piece 15 and rein orcing supports 16 and 17. 18 is a link member on the machine front for hitching the machine to-a tractor or otherwise. v

Suitably suspended by hen ers 19 from the frame 13 are screens 20 an 21 arranged one above the other and provided with sides 22 extending above the screens and adapted to provide side guards for a top floor or platform of slate 23. The fore oing portions. of the machine are particu arly illustrated in Figures 1, 2, 3 and 6.

At the inner top end of the screens is suspended by hangers 25 a delivery shoe 26 operatively arranged in relationship to sets of roller crushers-27 and 28, in turn operatively connected (see Figures 2, 6 and 7) to a double set of elevators 29 and 30 provided with conveyin and delivering means 31 adapted to receive weeds, clay, roots and the like from a scoop member 32 mounted between the lower end of the side casin memher 33 for the elevators at 34, and adapted, on the machine being moved forward, to scoop up the weeds from the ground and at the same time to partially dig a furrow therein. 7

This shoe scoop or cultivator member 32 can be raised or lowered by means of a bent horizontalarm 35 fixedly secured thereto and provided with a hole in its opposite end registering individually with a series of holes 36 in a vertical arm or blade 36 on the machine, the adjustable arm 35 being connected by links 37'and 38 to a lever 39 whereby it is operated, said lever being adapted to engage with a ratchet member 40.

The elevator side casing members 33 are secured to the machine frame at 41 and also supported thereon by hangers 42. For raising or lowering the front of the machine, a casterwheel 12 is operated by a lever member 42 connected through a lever arm 43 with a link 44-, in'turn connected to the arm 45 engaging the head of the caster d6.

Tiltably mounted at 48 on the end of the machine is a box 47 designed to receive therein material from the screen members 20 and 21 and the slats 23. This box is tilted, when full, to deposit its load by means of a cable 49 attached to the box at 50 and continued on pulle s 51 and 52 across the skeleton frame to be dually operated by A sprocket 'is provided a suitable foot control on the actor or otherwise to which the present machine 18 hitched. I

The bottom of the frame 10 is open and substantially hopper-shaped, as shown in Figure 3, to return the sifted earth to the ground and thus fill up the furrow made ori 'nally by the scoop member.

he mechanism of the machine for operating the elevators and fan is as follows: wheel 53 is keyed to the main axle and connected by a chain 54 to a sprocket-55 on a shaft 56 on which is mounted a sprocket, in turn chain-connected by a chain 58 to one of the elevator s rockets 59, in turn chain-connected to a ro er gear 60; The second elevator s rocket 61 is operated by he turned from left to right, while the other elevator sprocket '59 is operated to turn from right to left. The second sprocket 61 is connected by a chain 62 to a sprocket 63 on the shaft 64 provided with the endless chains 24 carrying the cross-pieces 23.

The rocking movement is im arted to the double screens by means of a vel gear 65 mounted on the main axle and adapted to mesh with a bracket-sup orted bevel gear 66 on the end of a cranks aft 67 in suitable hearings in the frame 10. This crank shaft with arms 68. and 69 suitably secured to the screen box and the delivery shoe, respectively, and by means of which, on the machine moving forward, a rockin motion is imparted to both these parts. lever member 70 is connected by a cable 71 to the skeleton frame and deslgned, on the machine moving u an incline, to be tightened, so as to retam the skeleton frame in perpendicular position.

It will be seen from the foregoing that I have invented a complete and slmply constructed cultivator and land cleamngl machine, the operation of which is as fo ows: The machine being hitched up to a tractor and started in a forward direction, the scoop member or shoe 32 is adjusted to suit the nature of the ground by means of a lever 39 in connection with it and a lever 42 for'the caster wheel 12. The earth, weeds, grass and all surface material is taken up by this scoop, delivered to the elevators and from them through the rollers 27, 28, to the delivery shoe, from whence it is forwarded onto the floor 23, where it is partially sifted; all the fine material such as clay, some of the weeds and the smaller stones assing through the slats onto the sieves, w ere it is again further sifted, and, finall the clay only being delivered through the ottom of the machine, while the smaller stones and some of the weeds are delivered into the tiltable box at the back of the machine; the lar er stones, remainder of the weeds being delivered overthe top of the box at the rear the chain 58 mes ing therewith to of the machine to the ound; As soon as the box .is full, it is ti ted, depositing contents in a mound to be burnt or otherwise disposed of, the sifted clay in the meantime beinglreturned to fill the furrow formed by the s co in the first instance, and thus leave the ground in good order and clean.

As many changes could be made in the above construction and many apparently widely different embodiments of myinvention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accom anying specification and drawings shall mterpreted as illustrative and not in a limitin sense. I

What I claim as my invention 15:
